A'pliieatiqn fried April 9, 190s, serial No. 310,767. Renewed January 26, 1909. serial No. 4f/4,332.

To all whom 'it may concern:

Be it known that I, JOSEPH H, GINET, Jr., a citizen of the United States, residing in Denver, in the-county of Denver and Stateof Colorado, have invented certain new and" useful Improvements in AddingMachines, of which the following is a full, clear, and

, exact descriptipn, reference being had to the accompanying drawings, forming partof this specification.

My invention relates to an adding machine of the nature of that lshown and described in elevation of the gearing end of the machine with the casing in transverse section and th'e governor gear wheel shown partly in section. Fig. V 1s a front elevation of the machine with the casing shown in vertical longitudinal section. Fig. VI is a rear elevation of the machine with the casing shown in vertical longitudinal section. Fig. VII is a view partly in elevation and partly in vertical section of a sei'ies of the counting wheels and the actiliating.)r and controlling members associated therewith. Fig. VIII is a vertical section taken on line VIII-VIII, Fig. VII. Fig. IXis a -view partly in elevation and partly in vertical section of the counting wheel controlling mechanism. Fig. X is a perspective view of the digit wheel controlling member in detached condition. Fig. XI is a perspective View of one of the transfer members associated with the counting wheels. Fig. XII is a perspective view of one of the digit wheels and the swinging arm` by which it is carried.

1 designates the base of my machine which is surinounted by a casing 2 of suitable shape and which is provided with a plurality of sight openings 3 through which the numerals on the counting wheels of the machine may be observed, and also with a plurality of slots or openings 4 and 5 in which the various keys of the machine operate.

6 and 7 are forward standards mounted upon the base 1 and adapted vto support the counting wheels and the operating and controlilling mechanism directly associated there- Wit y 8 and 9 are standards niounted upon the base and adapted to support the motor of the machine and 10 and 11 are standards also mounted upon the base and adapted to support' the digit mechanism of the machine.

Referring next to the motor of the ma.

chine: 12 designates a main-spring and 13 a main-spring shaft that is jouriialed in the standards 8 and 9 and which is adapted to receive power from said spring. One end of the main-spring is connected to said shaft and the other end is'held in a fixed position by attachment to a member rigidly secured to either of the standards 8 and 9 or any other part to which it can be conveniently applied. The main spring may be wound by rotating the shaft 13 through the medium of a suitable key applied thereto and when this is accomplished the spring is held under tension by a pawl 14 (see Figs. II and VI) that engages a ratchet wheel 15 on the main-spring shaft, the pawl being preferably held in engage ment with the ratchet wheel by a spring 16.

. 17 designates a master wheel fixed to the main spring shaft and by which the pawl 14 is carried. The master wheel meshes with a pinion 1S that is fixed to a primary driving 'shaft 19 that is journaled in the standards 10 and Il and extends to the side of the ina-- chine farthest removed from its motor. The primary driving shaft has fixed to it a primary driving gear wheel 20 that is arranged in mesh with a pinion 21 which is journaled 24 designates a governor gear wheel that is I loosely mounted upon a stub shaft 25 seated in the forward standard 7 and with which the secondary driving gear wheel 23 meshes.

26 is a transmission gear wheel located alongside of the governor wheel 24 and also loosely mounted upon the shaft 25. rlhe governor gear wheel 24 and transmission gear wheel 26 are united to cach other by a governor spring or e ualizing spring 27 (sce Fig. IV), one end of w iich is secured to one of said wheels while the other end is secured to the other `wheel. The transmission 'gear wheel 26 is arranged to drive certain arts of ,the mechanism to be presently descri ed and the power for the operation of `said wheel is derived from the main-spring 12 of the machine wlaich is communicated thereto through the governor wheel 24. The 'object of thus communicating the power to said transmission wheel is to maintain an equal power action upon the transmission wheel at all times irrespective of the degree of tension in the main spring of the machine which naturally decreases as the spring expands in its unwinding action, and is increased when the main spring is wound. It will be seen that by employing the governor or lequalizing spring 27 said spring is put under tension each time that the governor wheel is rotated by the secondary driving wheel 23 to store power in the spring inorder that it will thereafter act as a supplemental power member to drive the transmission gear wheel 26 with uniform action upon each operation. It should be here mentioned that for the purpose ofsecuring the action of the governor spring the governor gear wheel 24 is held from rotation in a manner to bepresently explained while said governor spring is acting to rotate the transmission gear wheel 26.

28 designates a tumbler shaft that is journaled in the standards 10 and 11 and to which is fixed a series of toothed wheels `29 corresponding in number to the numerals 1 to 9 inclusive. The tumbler shaft 28 has fixed to it a gear wheel 30 that is arranged in mesh with the transmission gear wheel 26 so that said transmission gear wheel will act to operate said tumbler shaft.

31 designates a trip bar arranged parallel to the tumbler shaft 28 and which is provided with arms 32 and 33 that are rockingly supported by a rod 34 mounted in the standards l() and 11 (see Figs. Il and III). The trip bar 31 is acted upon and normally held by a spring 35 surrounding the rod 34 and having one of its ends fixed to a portion of the trip bar and its other end held in a fixed position by attachment to a stationary part of the machine. The tumbler shaft 28 has rigidly mounted thereon a ratchet wheel 36 and the arm 32 of the trip bar 31 is provided with a pawl `32 that is adapted to be normally maintained in engagement with said ratchet wheel 36 under the influence of the spring 35. The arm 33 of the trip bar 31 extends beyond the trip bar supporting rod 34 forwardly and laterally, and terminates in a detent arm 33 that is adapted to engage the governor wheel 24 to hold said wheel from rotation while the governor spring 27 is act-- ing to drive the transmission gear wheel 26 in the manner previously explained. 37 designates a rod mounted in the standards 10 and 11 at the rear of the machine.

38 are swinging arms corresponding in number to the number of toothed wheels 29 on the tumbler shaft 28, each of these arms being rokingly'supported by the rod 37 and having their forward free ends superimposed above'tlie tumbler shaft 28 and the tri bar 31. The swinging arms 38 have joui-na ed in their free ends digit wheels or segments 39 that are adapted to be brought into meshing Vengagement'with the toothed wheels 29 on the tumbler shaft 28.` The digit wheels are provided with varied numbers of teeth according to the particular digits from 1 to 9 inclusive, in order that they will determine the degree of rotation of the tumbler 'shaft 28 when they enter into mesh with the ,meshing with the toothed wheels 29 on the tumbler shaft'28. When the digit wheels are retracted under the action 'of said springs the degree of rotation of said wheels is restricted by stop fingers 38 projecting laterally from the swinging arms 38 and over the digit wheels and adapted to be engaged by thc forward shoulders 39 of the digit wheels. I 41v and 42 are respectively upper and lower apertured guide bars supported by the rear standards 10 and 11, and 43 is a catch bar located between said guide bars and also supported by said standards. r

44 designates main key stems that operate through theI guide bais 41 and 42 and each of which is provided at its rearedge with a notch 45 (seeFig. X) that receives a member to be hereinafter more particularly referred to. The mainkey stems are pivotally connected at 46 to the swinging arms 38 in order th'at said swinging arms may be depressed when the key stems are moved downwardly for the purpose of lowering the digit wheels into engagement with the toothed wheels 29 'on the tumbler shaft 28, and also for the purpose ofreleasing the spring controlledfpawl 32 from engagement with the ratchet wheel 36 to permit` rotation of said tumbler shaft, the said pawl releasing action being secured due tothe operation of the swingingarms against the trip bar 31. A part of the'inain key stems 44 extend in direct vertical lines through the apertures 5 in the casing of the machine at its top andare provided with keys 47. The remainder of said key stems terminate above the upper guidebar 41 and within the casing and have attached to them the L-shapedy bars 48fthat are rockingly ivoted to them at 50 (seedotted lines Fig.`

Il) and extend upwardly from a position in front of saidv pivotal points and through the I top of the casing of the machine-into juxtaposition to the entirely vertical main key esame E:

stems 44. Each of the key bars 48 is provided with a key 47. `'lhe'object in using the L-shaped key bars is to so position all of the keys 47 that they may be readily operated Without interference or without a Wrong key-l being struck by the operator while-at they same time economizing in the length or breadth of the machine. r

51are lift springs by which the main key stems 44 are elevated after they are depressed, these springs being each connected to said key stems at one end and having their other end attached to the upper guide bar 41. 52 designates controlling or sup lemental key stems that are located alongside of the main key stems 44 and have slot and pin connection therewith (see Fig. X), which, with the parts associated therewith, and to be now described, constitute guard mechanism for reventing retrograde rotation of the digit W eels When an unsteady pressure is exerted upon the main key stems or a slow y pressure 1s exerted thereu on instead of a ,quick positive' ressure ach controlling stem has pivote to it at 53 a dog 54 that includes a awl 55 which extends into proximity wit the lperiphery of the corresponding digit whee 39, and is adapted to be engaged by the shoulder 39a ofsaid Wheel 3-0 after the Idigit wheel hasl partaken of the proper rotation to overn the degree of rotation of the toothe y wheels 29 according -to the particular digit wheel. Each dog 54 also has a catch arm 56 that normally rests in a '35 notch 52 Vin the corresonding controlling stem 52 and inthe note 45 of the adjacent main key stem. Each dog 54 is yieldingly held by a spring 57 whereby the pawl 55 is normally maintained in juxtaposition with the eriphery of the corresponding digit Wheel) and 4the catch arm 56 is normally maintained in the notches of the main key stem and controlling stern to which it applies. 58 desi nate lock members that are preferably of ell-crank shape and are ivoted to v the controlling stems at 59. Eac of these lock members is provided with a shoulder 60 that is adapted to engage beneath the catch y 'bar 43 when the key stems and controlling '-50 stems are depressed, the shoulder being held in such position due to the action of a p'ull lspring 61 attached to thepressure arm 58 of t e lock member and which serves to hold said ressure arm in a lowered position,

55 where y it is caused to retain the pawl 55 of the dog 54 immediately beneath it against the periphery of the digit wheel that it surmounts, and the catch arm 56 of said dog Vin the main key stem and controlling stem .60' notches 45 and 52. `When each main key stemis de ressed to carry the corresponding digit whee into'mesh with the corresponding tumbler shaft Wheel 29 beneath it, the swin ing arm 38 that carries said digit wheel 1s 6'5 moved downwardly and presses against the trip bar 31 with the result of moving said trip'bar and withdrawing its pawl 32 from engagement with the ratchet wheel 36 in order that the tumbler shaft may be rotatedby the power mechanism of the machine.

may be hereistated that when this action ries therewith the corresponding controlling stem 52, due to the catch finger 560i the dog 54 carriedby said controlling stem being situated in the adjacent notches 45 and 52 lo- 80 cated in said stems.A At the time that each digit wheel enters into mesh with the correspending tumbler shaft wheel 29l the lock member is'drawn forwardly under the action of the ull spring 61 connected to its ressure 85 arm, tris movement being permitte due to the sl oulder 60 of the lock member being lowered to the lower edge of the catch bar 43 in juxtaposition thereto. Upon this action taking )lace the shoulder 60 moves beneath said 90 eatc bar and serves to momentarily lock or retain the key stems in a lowered position, in whichposition they are held until the digit wheel has completed the required movement according to the number of its teeth. Immediately upon the digit Wheel com letin its rotation the shoulder 39 of the igit w eel strikes against the rear -side of the pawl 55 presented to the perimeter of said Wheel,with the result of tripping said pawl upwardly whereby it is caused to exert an upward pres- -sure against the pressure arm 58 of the'lock member 58 by overcomin' the p ull spring 61 so that the shoulder 60 o? said lockmcmber is rocked from its position beneath -the catch bar 43. When this action occurs'the main key stem is promptly moved upwardly under the action of the ull spring 51 attached thereto and the digit Wheel withdrawn from the tumbler shaf t Wheel 29 with which it previouslymeshed. Each dog 54 is tripped by the actuation of its pawl 55 the catch finger 56 of said dog is removed from the notches 45 and 52 in the main and controlling stems 44 and 52, whereby said controlling stem is released to be drawn u Wardly under the action of the corres on ing ull spring 5'?"7 in order` that when t e main igey stem resumes its u lifted position the notches in the vstems will ey in lalinement to again receive the catch finger, thereby placing .the parts in condition for the next operation.

- The digitwheel mechanism that has been described constitutes the means for overning the actuation of the counting whec mechamsm due to its controlling the transmission wheel 26 and said transmission wheel serves to'drive the counting wheel mechanism that will next be described. y

62 designates a countingwhcel shaft that 139 is journaled in the forward standards 6 and 7 and which 'has fixed thereto a pinion 63 arranged in mesh with the transmission gear wheel -26 to be driven thereby, On the counting wheel shaft is mounted a plurality of counting wheels l64 that bear numerals from 1 to 9 inclusive and 0. Any desirable number of these lcounting wheels may be used but in the drawings I have shown seven of such wheels to provide for the addition of numbers into the millions, the 4counting wheel at the extreme right being the units wheel and the one at the extreme left being the millions wheels. The counting wheels are Aloosely mounted upon the counting wheel shaft and said shaft is provided intermediate of the counting wheels with splines 62 (see Figs. II and III). Each of the 'counting wheels is provided with a gear member 65 having peripheral teeth and in the side of eachof the gear members are pockets 66 corres onding in. number to the number of numera characters on the perimeterv of the counting wheel. counting wheels also provided with a notched transmission arm 67 (see Figs. VII

and VIII) projecting laterally from the wheel at its perimeter and adapted to engage a transmission member to be hereinafter mentioned. l f f l 68 are tumblers which are slidably fitted to the counting wheel shaft adjacent to the various counting wheels to which they correspond, the said tumblers being held from rotation relative to said shaft by' engagement I with its s lines 62. The main ortionof each tumb er is in the form of a col ar having an annular groove 69 therein and each tumbler Vincludes an arm 7()v which is provided with a pin 71 adapted to enter either of the pockets 66 in the counting wheel gear mem- I ber towhieh said tumbler corresponds.A The office of the tumblers 68 is that of imparting rotation to the different counting wheels according to whichever tumbler is thyown into enga ement with its particular counting whee to drive it during the rotation ofthe counting wheel shaft on which all of the counting wheels are loosely mounted as before stated, while the tumblers are slidable on but not rotatably fitted to the counting wheel shaft.

72 designates an upper guide bar and 73 a lower guide bar, both of which are supported by the forward Vstandards 6 and 7 and are apertured" for the, operation of key bars therein.

74 designates vkey bars corresponding in number to the number of counting Wheels and arranged to operate in said guide (bars. lThese key bars extend through the apertures 4 in the casing 2y and are provided exterior of the casing with keys 75. Earh keyrbar74 is subject to the action of a lift spring `76 that is connected at one' end to the key-,bar

Each of the and has its other end attached to a fixed part of the machine, such for instance as a rod 77 mounted in the forward standards 6 and 7 (see Figs. II and III). Each key bar 74 is provided with a cam arm 74 extending in a rearward direction from the bar and each of said bars isalso provided with an upper throw pin 74@l and a lower throw pin 74".

78 designates a lower shifter supporting bar rigidly mounted in the forward standards 6 and 7 at the rear of the counting wheels 64 and alongside. of the key bars 74, the said' barsbeing provided with vertical slots 7 9 in which the throw pins 74b of the keys 75 are adapted to operate during their vertical movement.

8() are shifters, the bodies of which arefitted tothe shifter suportinvfbar 78 to which they are prefera yV held by lifps 81 that embracethe bar. In the body o each shifter' 80 is a diagonally'extending slot 82 in 69 as seen in Figs. II, III, V and VII. When either of the keyv bars .74, is depressed, whether it be that corresponding to the units, tens or any other counting wheel in the machine, the corresponding shifter isreciprocated on the lower supporting bar 78 to carry the corresponding tumbler toward its counting wheel and cause the tumbler pin 71 to enter into a pocket 73 of the mating counting wheel, thereby causing the counting wheel to beY locked from rotation on. the vcounting wheelshaft and rotate withv the shaft, due to the engagement of the tumbier'therewith'.

84,designates an ulpper shiftersupporting bar that is reciprocal u in the forward standards 6 and 7 in order that@ in nelly-ofthe upper shifter s up Inediat'ely above t e lower shifter supportingv bar 78 and alongside ofy the key ars 74. The upper shifter vertical ,slots 85 in vwhich the key bar throw pins 74a operate. Y 'i 86 are shiftersreciprocally fitted tothe upper bar 84 and. preferably held thereto by lipsv 87 that embrace the bar. In th'ebody of each shifter 86 is a diagonal slot 88 1n ies of counting wheels. This which the corresponding key bar .throw pinorting bar is located imbe moved to and fro longitudil 1 15 supporting bar containsl J 'extending flange 97 arranged in the on the rod -90 intermediate of the various counting wheels, said members being arranged both for reciprocation and rotation on said rod. Each of the transfer members is provided with an annular groove 92 to which a corresponding bifurcated shifter arm 89 is fitted in order that the transfer member may be reciprocated into'and out of engagement with the counting wheel it `acts upon. Each transfer member also has a pinion 93 adapted'to be engaged by the transfer arm 67 of the count-ing wheel from which transfer is to be made to the counting wheel of the next higher denomination, and each transfer member also has a pinion 94 that is arranged to be thrown into engagement with the gear member 65 of the counting wheel to which transfer is to be made when the transfer arm 67 engages th'e transfer member pinion 93. Each transfer member 91 also includes a multiploV arm stop wheel 95 that constantly occupies a position above the perimeter of the counting wheel to which it applies and serves to hold 'the transfer member associated with the counting wheel from which transfer is to be made from rotation until transfer from one counting wheel to another is made upon the transfer arm 67 of the transferring wheel is brought into registration with the transfer member pinion 93, at which time the stop wheel is permitted to enter into said transfer arm due to the counting wheel being slightly cut away at the location of said transfer arm, as seen in Fig. VIH.

When either of the key bars 74 is depressed, the throw pin 74a carried thereby operates in a vertical slot 85 in the shifter supporting bar 84 and also in the diagonal slot 88 of the corresponding shifter 86 as a result the transfer member to which said shifter is fitted is thrown toward the right and out of engagement with the corresponding counting wheel at the left thereof in order that said counting wheel may have rot ation imparted thereto, through rotationof the counting wheel shaft, and act in turn upon the next adjacent countingwheel toward the left by transferring to it through the medium of the transfer member at the left thereof.

96 designates a lock bar that is rockiiigly mounted upon the rod 77 and located at the rear of the key bars 74, this lock bar being provided at its upper edge with a forwardly ath of travel of the key bar cams 74. v T ie lock har is normally held with its flange piessed against said key bars by a spring 98 that bears thereagainst. When either of the key bars is deiressed its` cam 74' operates to throw said fock bar rearwardly, and the cam then passes into a )osition beneath the lock har flange with tie result that said flange serves to hold the key bar depressed.

lhc shifter 83 is therefore retained in a position to hold the corresponding tumbler 68 to vwhich it is fitted in engagement with the counting wheel to which it is moved.

When it is desired to count into. a higher or lower denomination the key bar 74 corresponding to the denomination in which counting is to be accom lished is depressed without the necessity of first releasing the reviously depressed key bar, which is reeased due to the cam of the latest depressed key bar acting to tri the lock har 96 and release the previousiyT depressed key bar, which is released due to the cam of the latest depressed key bar acting to trip the lock bar -96 and release the previously depressed key bar, which is returned to its upliftedposition by its pull spring 76 before the cani'74 of the last de ressed key bar is engaged by the lock bar. 'ghe pinions 94 of the transfer membersserve to prevent accidental rotation of all of the counting wheels except the units counting wheel due to their engagement with the gear members of said wheels, and therefore no other locking means for preventing accidental displacement is required. The unitsfcounting wheel is not controlled by a transfer member and for the purpose of preventing accidental displacement thereof, I form upon the arm of the upper shifter corresponding to said units wheel a detent 89 (see Fig. II), that is adapted to enter into engagement with said gear member when the units Wheel shifter is shifted and the units wheel is to be operated.

For the purpose of freeing the counting wheels and at the same time either of the 4key bars 74 that may be at the time depressed, vin order that the counting wheels may be returned to zero, I' employ the following mechanism: 99 designates a slide reciprocally supported by the`front standard o' and provided with a push rod 100 which bears a knob 101. with a horizontal cam 102 that projects into proximity with the first key bar 74 at the side of the machine at which said slide is located and which is adaptedto exert pressure against said key bar to move it laterally when the slideis moved rearwardly. When this engagement of the cani and key bar occurs the key bar is rocked toward the opposite sidev of the machine and, due to its upper throw pin 74a being seated in the upper shifter support-ing har S4, said shifter supporting bar is moved toward the right, with the result of rocking all of the key bars in a corresponding direction, a movement that is occasioned due to the presence of the upper The slide 99 is provided throw pins of allthe key bars in said sup- When the supporting bar is 92 are all withdrawn from the gear members 65 of the counting wheels. The, counting wheels are thereby freed to permit of their being rotated freely on their shaft to .bring the zero character on the wheels into view beneath the casing sight openings 3.

103 is a frame rockingly mounted beneath the counting wheels upon a rod 104 supported bythe forward standards 6 and 7. .In

this frame is journaled a shaft 105 on which are rigidly mounted a series of friction wheels 106 corresponding in number to the number of counting wheels and adapted to be brought into frictional engagement with said counting wheels.v The frame. V103 has fixed toit an upwardly extending arm 107, the upper free end of which is located at the rear end of the slide 99 and is adapted to be acted .upon by said slide to throw 1t rearwardly. When the slide is moved rearwardly it operates against the arm 107 and by so doing causes the frame 103 to be rocked upwardly and the-friction wheels to be moved into contact with the counting wheels. The shaft 105 is then rotated and the counting wheels are turned by the friction wheels until they are brought to the desired adjustment. The friction wheel shaft has applied to it a kno-b 108 that is located exterior of the casing of the machine and by which said shaft may bev readily turned. i The upper shifter supporting bar 84 has connected to it a return spring 109' (see Fig. III) by which it is retracted after'it has been shifted to accomplish the'release of the counting wheels and the slide 99 has connected to it' a return spring 110 (see Figs. II and III) by which it is retracted.

I wish to call'particular attention to the arrangement of the key stems and the keys associated therewith by which the digit wheel mechanism of my machine is thrown into action. These key stems and their keys are, as seen most clearly in Fig. I, arranged in two banks in which the bank nearest the front of the machine contains four keys and..

the other or rear bank contains five keys, tbus completing the series' of digits. This arrangement of keys is a highly important one in that it provides for much more efficient and rapid actuation of the digit mechanism through the medium of the key stems, due to their arrangement providing for the operator of the machine placing the four fingers of a hand upon the four front keys during his adding operation and reaching rotation of said gear wheel and therefore rotation of the remainder of the driving mechanism of the machine associated therewith during the act of winding the main spring of the machine, thereby preventing said gear wheel from acting upon the equalizing or governor gear wheel 24 and causing the-A equalizing spring 27 associated therewith to be unwound, an action that 'would result in the absence of any means 11o-restrain the driving mechanism while the main springis being wound.

1 12- is a stop for restricting the movement of the'detent. I claim:
